Six different date rules cover Mother’s Day around the world. The 2nd Sunday of May (May 10 in 2026) is the global default — observed in roughly 110 countries from the United States, Canada, Australia, and most of Europe through China, Japan, India, and most of Latin America and Sub-Saharan Africa. The Arab world celebrates on March 21 (spring equinox, since Egypt’s 1956 reform). France and most of Francophone Africa wait until the last Sunday of May. Iberia and Lusophone Africa use the 1st Sunday of May. Post-Soviet states and parts of the Balkans fold Mother’s Day into March 8 International Women’s Day. And ~30 countries — Russia, Mexico, the UK, Indonesia, Thailand, Norway, Bolivia, Argentina, Nepal, Poland, Belarus, and others — pick their own dates for their own reasons. This post maps every country and unpacks each rule cluster.

Female labor force participation rates by country in 2025, per ILO modelled estimates published in the World Bank’s April 2026 WDI batch. Madagascar (82.9%), Solomon Islands (82.3%), Nigeria (80.7%), Tanzania (80.3%), and Burundi (79.5%) lead the world — far above the Nordic cluster at ~60%. The MENA region dominates the bottom: Yemen (4.7%), Afghanistan (5.1%), Iraq (10.9%), Syria (12.7%), Iran (14.0%), Algeria (14.1%), Jordan (16.0%), Egypt (18.5%).

240 million people live with chronic Hepatitis B globally, with fewer than 5% receiving treatment — per the WHO’s Global Hepatitis Report 2026 (released April 2026). West Africa has the world’s highest prevalence: Mali (13.9%), Sierra Leone (13.5%), Guinea-Bissau (12.3%), Cameroon (11.5%). Indonesia (17.5M cases) and Nigeria (14.4M) carry the largest absolute burden. Western Europe and Latin America sit under 1%, the result of universal infant vaccination since the 1990s. The WHO’s 2030 elimination target is now off track — birth-dose vaccine coverage in Africa is under 20% against a 90% goal. This post maps every country’s chronic HBV prevalence and surfaces where the burden is concentrated.

World Bank’s April 2026 WDI update maps the global renewables divide. Bhutan (100%), Lesotho (99.8%), Costa Rica (99.4%), and Norway (99.1%) lead the world, all driven by hydropower.

The decade’s biggest transitions: Denmark from 32% to 79% (offshore wind), the UK from 7.7% to 40.2% (offshore wind), Cambodia from 4% to 56% (hydro). The G20’s biggest economies — China 28%, US 20%, India 19% — still get the bulk of their electricity from fossil fuel. This post maps every country’s 2021 renewable share and identifies who’s moving.
